One of the things I have observed in my advanced age -- 53 seems young to me but I am ancient by human standards -- is that women don't really do such a bad job in picking the male vectors for their DNA.

I think it might be because the male's Y chromosome DNA is irrelevant to the female offspring -- it's as it if doesn't exist. Our double X chromosomes can't "see" it.

On the other hand, all of our offspring, whether male or female, carry our mitochondrial DNA (mDNA or mtDNA) and the male contributes zero towards that.

Very weird that.

Male to male to male to male, ad infinitim, Y chromosome skips all females.

While female mitochondrial DNA is contributed to all offspring, whether female or male. You have none of your father's mDNA, all of it is your mother's, and all of your father's Y DNA, none from your mother or her father.

At any rate, the children turn out fine, despite the fact that the dad's a dud. Or at least start out fine. They may not end up fine but that's not a genetic story, really.
